vegetarian burritos - what are your favorite ingredients?

I want to make homemade vegetarian burritos and I was hoping the Food52 community might be able to help me come up with some new additions to my regular rice and beans. To be clear, I'm happy with the black beans and rice that I currently use, I'd like some of your favorite add-ons e.g. salsa, guacamole, condiments, pickles. Please share - Thank you!

To my rice I like to add chopped plum tomatoes & fresh jalapenos & radishes, ripe olives, a handful of frozen corn, and lots of shredded cheddar/pepperjack. Sometimes its nice to skip the usual black beans and add a smear of canned refried beans to help it all stick together.

We have a little restaurant in town and I always get their veggie burrito because in addition to beans, rice and salsa they put all kinds of grilled veggies -- onions, summer squash, zucchini, mushrooms, peppers -- and lots of avocado slices. So whenever I have leftover grilled veggies I try to recreate their burrito.

Okay, this is my contribution http://food52.com/recipes... Although the recipe calls for pork belly (which is really good) you can leave that out if you prefer.
Eggs are also really good in burritos unless you are a vegan.

I love to roast cubed sweet potato, zucchini, bell peppers, and onions (and jalapenos if you like it spicy) with olive oil, salt, and cumin. Once they are roasted, I toss them in lime juice and chopped cilantro, then add black beans. Super yummy and filling vegetarian burrito! Add a little creme fraiche and avacados and you're in heaven :)

If I know I'm having a busy week, I'll cook up all my ingredients on one night and eat leftovers all week. I try to recreate the "chipotle burrito bowl" so I make rice, black beans, corn, sauteed green peppers and onions, cheese, sour cream, and guacamole. I could eat this every day forever

Thanks to everyone for all of your great ideas! I decided to try making a homemade hot sauce out of a jar of hot peppers I've been fermenting and it was delicious with the rice and beans. I took about 10 peppers and rough chopped them, added a bit of filtered water and white wine vinegar, and blended well with my immersion blender. Delicious!

A little late, but I love tempeh cooked with a little veggie broth, liquid smoke, garlic, maple syrup and soy sauce until glossy. That is good with everything - on sandwiches, as "bacon" with breakfast, burritos, you name it.
